Interface Module for a Communication Control Device, Transmitting/Receiving Device for a Subscriber Station of a Serial Bus System, and Method for Communication in a Serial Bus System

4. The interface module according to claim 3, wherein the interface module is configured such that the first and second multiplexers are controlled by the same control signal.

8. The communication control device according to claim 7, wherein an operating mode signaling signal signals to the interface module into which operating mode the transmitting/receiving device is to be switched as a function of the communication on the bus.

10. The communication control device according to claim 7, wherein the communication control module is configured to produce the transmission signal in the first communication phase with bits having a first bit time that is greater by at least a factor of 10 than a second bit time of bits produced by the communication control module in the second communication phase in the transmission signal.

12. The transmitting/receiving device according to claim 11, wherein the transmitting/receiving module is configured to transmit the transmission signal as a differential signal onto the bus, and wherein the third port is an input-to-output switchable port and is configured for signaling a standby state to the transmitting/receiving device, in which state no communication occurs on the bus.

13. The transmitting/receiving device according to claim 11, wherein a signal received in the first communication phase from the bus is produced with a different physical layer than a signal received in the second communication phase from the bus, and wherein, in the first communication phase, it is negotiated which of the subscriber stations of the bus system receives an at least temporarily exclusive, collision-free access to the bus in a subsequent second communication phase.
